Slots seem to be rigged

I dont know what to say but for the past 2 weeks all I have been doing is depositing constantly with nothing in return which is now making me afraid to deposit cause no matter how much I deposit it does nothing but go down neither do I get to enjoy my spinning. You guys can chow me 400 then give 25 free spins believe me from those free spins I get nothing. Not sure if you recharging me from the 800 I won a month and half ago of which prior to that I had lost more than a grand. Reels are just a disaster of late . I work hard for every voucher I buy be it it's a small amount . You cannot reap us off like this. Its wrong
